Iberogast is a natural prokinetic (can buy on amazon), here's the contents. Peppermint leaves worry me a bit (normaly not good for gerdies) and it stimulates bile production. I still may give this a try.
Iberogast is comprised of the following 9 ingredients: Iberis amara, Angelica, Chamomile, Caraway Fruit, St. Mary’s Thistle, Balm Leaves, Peppermint Leaves, Celandine, and Liquorice Root.
